1. An apparatus to provide suction to a wound site through a drape covering the wound site, the apparatus comprising:
- an applicator configured to be positioned over an opening in the drape, the applicator comprising;
a flexible layer having an upper surface and a lower surface;
an adhesive provided on the lower surface of the flexible layer configured to seal the applicator to the drape; and
a removable protective release layer provided over the adhesive on the lower surface of the flexible layer; and
a bridge comprising;
a proximal end provided with a connector configured to provide fluid communication with a source of negative pressure,an enlarged distal end having at least one aperture therethrough, the enlarged distal end of the bridge coupled to the applicator,an upper wall and a lower wall extending between the proximal end and the enlarged distal end, andat least a first channel and a second channel positioned between the upper wall and the lower wall such that at least one of the first channel and second channel is configured to provide fluid communication between the at least one aperture and the connector;
wherein the flexible layer of the applicator is coupled using an adhesive to the enlarged distal end of the bridge.
